Solr 6.4.1 config

Since I was recently asked off-list - thought I'd make this available if
it will help anyone else.  Attached is my (I hope) working 6.4.1
config.  Also some instructions:

First, you have to decide if you're running in standalone or cloud
mode.  Standalone is simpler, but I seem to be having better luck
running in cloud mode - even though I'm only using a single
server/core/shard/collection/whatever.

I've attached my config.  Unzip this somewhere convenient - I will
assume "/tmp/solr-dovecot".  You may want to tweak it - this is
adapted
from my version 4 config and is set for English.  If you look in
solrbasedir/example/files/conf/lang or
/solrbasedir/server/solr/configsets/basic_configs/conf/lang you'll find
alternatives for "stopwords.txt" - I simply copied the
"stopwords_en.txt" file directly to "conf/stopwords.txt".

Assuming you extracted the Solr distribution to a base folder, such as
/opt/solr-6.4.1, change to that folder.

Then execute (again, /tmp/solr-dovecot is the path you extracted my
config into):

bin/solr create_collection -c dovecot -d /tmp/solr-dovecot

That should create a minimal cloud instance.  Then start it:

bin/solr start -c

And hopefully...you'll have a running Solr server.  Assuming that's the
case - since you've now created a "named" collection you have to
specify
that for Dovecot. So the fts_solr parameter in 90-plugin.conf needs to
be something like:

fts_solr = break-imap-search url=http://ser.ver.ip:8983/solr/dovecot/

Restart Dovecot...and with luck you're searching now.

Hope this helps somebody!
